tslayer Wrote:Topfs2, I thought it was vsync too, but I'm pretty sure I have it enabled as well. I also have an 8600GT.

FYI, it uses one core at 100%. Not both.

topfs2 Wrote:Sounds like vsync issue.

I have 8800gts and 5600fx, never 100% nor the issue slight is having

But slight which programs have you tried that are more advanced and uses shaders?
Warsow, Nexquiz, Saurbraten or ET:QW?
The 3 first are free and should be available in repo and might prove if it's driver related? Still games tend too use up all cpu

Thx

I must excuse myself, I have the problem aswell

I've too double checked and the applet tells me I have vsync on and such but I still believe it might be related somehow as video does bring the percentage down, anyone sure vsync work as intended on 8xxx series?

100% on one core applies seeing as XBMC only uses one thread for the rendering, and without vsync it prob. goes wild might be applet that cannot do vsync well, anyone tried it with xorg.conf?

You only need the "export set __GL_SYNC_DISPLAY_DEVICE=DFP-0" part if you're running multiple displays. Replace "DFP-0" with the X device that you actually watch on (I have a second little LCD panel on my media centre pc so I don't have to turn my projector on just to change music or whatever)

Hi,
I've got the same problem with XBMC svn (from ppa repository) and Nvidia GeForce 7300 LE. I tried both VBLANK variable and NoFlip Option, but my CPU still remains near to 100%. Can Someone help me, maybe pasting their xorg.conf file? I don't use DM, I just start XBMC using "xinit xbmc".

I try to paste your xorg.conf section, but nothing changes.
Can you help me to find the source of the problem? I checked the log and it seems that everything is fine. I really don't know where look at.
